Namespace: ILNumerics.Drawing.Plotting
Assembly: ILNumerics.Toolboxes.Drawing2 (in ILNumerics.Toolboxes.Drawing2.dll) Version: 5.5.0.0 (5.5.7503.3146)

Syntax

Copy

public ShapefileReader(
	string pathMainFile,
	string pathIndexFile
)

Public Sub New ( 
	pathMainFile As String,
	pathIndexFile As String
)

Dim pathMainFile As String
Dim pathIndexFile As String

Dim instance As New ShapefileReader(pathMainFile, 
	pathIndexFile)

Parameters

pathMainFile: Type: SystemString
is a string that contains the absolute or relative path to the main file (.shp) of a shapefile.
pathIndexFile: Type: SystemString
is a string that contains the absolute or relative path to the index file (.shx) of a shapefile.

Exceptions

Exception	Condition
ArgumentException	If the input parameter [!:pathMainFile] does not lead to a .shp file.
ArgumentException	If the input parameter [!:pathIndexFile] does not lead to a .shx file.
ArgumentException	If the provided shapefile does not contain the shape type polygon.
ArgumentException	If the provided shapefile is empty.

Remarks

This class produces a cell that contains the coordinates and indices for each record of the shapefile.

Currently, it is only possible to read shapefiles that contain the shape type polygon. It is very important to make sure that the main and index file belong to the same shapefile. This is usually indicated by the same file name. Otherwise contents might not match and will produce an exception.
